Abstract:
We present the first analytical inspiral-merger-ringdown gravitational
waveforms from black-hole (BH) binaries with non-precessing spins. By matching
a post-Newtonian description of the inspiral to a set of numerical calculations
performed in full general relativity, we obtain a waveform family with a
conveniently small number of physical parameters. The physical content of these
waveforms includes the "orbital hang-up" effect, when BHs are spinning rapidly
along the direction of the orbital angular momentum. These waveforms will allow
us to detect a larger parameter space of BH binary coalescence, to explore
various scientific questions related to GW astronomy, and could dramatically
improve the expected detection rates of GW detectors.
